In Traditional Chinese Medicine the sour flavor in sauerkraut causes contraction, gathering and absorbing in the body. It is most active in the liver and gallbladder where it counteracts the effects of rich, greasy foods. It acts as a solvent to break down fats and proteins. The sour flavor aids in digestion by raising stomach acid which helps dissolve minerals and vitamins for increased assimilation of the nutrients. It also promotes regular bowel movements! Incorporating 1-2 tbsp of sauerkraut with every meal not only benefits your digestion but also adds a new dimension of flavor to the dish!
